Balloon kyphoplasty for aged osteoporotic vertebral compressive fractures using instruments made in China

Objective To evaluated the efficacy and safety of balloon kyphoplasty in treatment of painful osteoporosis vertebral compressive fractures using instruments made in China.Methods Sixteen cases of painful osteoporotic vertebral compressive fractures,involved 19 vertebrae.Under X-ray fluoroscopy monitoring,the inflatable balloon were inserted into the fractured vertebral body via transpedicular route bilaterally.The balloon was inflated with injected contrast agent,restored vertebral height and formed a cavity within vertebral body.The cavity was than filled with bone cement in toothpaste period.The postoperative symptoms and the radiographic finding of vertebral height were observed.Results Balloon kyphoplasty was successful in all 16 cases with dramatic pain relief within 48 hours after the procedure.No clinical complication was found.The posttreatment mean anterior and mid portion of the vertebral body heights were(10.7±3.5)mm and(5.4±2.7)mm respectively,while that of the pretreatment were (14.8±4.1)mm and(10.4±4.4)mm, respectively(t=3.96,5.37;P0.01).Before the procedure, the mean Kyphosis was(22.4±5.8)°,after the procedure,the mean kyphosis was measured(12.1± 5.3)°(t=5.93,P0.01).Leakage of a small quantity of bone cement occurred at one level.Conclusion kyphoplasty using instruments made in China for painful osteoporotic vertebral compressive fractures was effective and safe.
